GEORGE W. GARNAR, OF FLU SHING, NEW YORK.

EMBOSSlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 265,057, datedSeptember 26,. 1882. Application filed August 4, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, GEORGE W. GARNAR, ofFlushing, in the county ofQueens and State of New York, have invented an Improvement inEmbossing-Machines, of which the following is a specification.

Before my invention the surfaces of leather,

been embossed by the act-ion of rollers and by flat plates applied insuccessive impressions; but in consequence of the great force requiredthe rollers were liable to spring and make the impression imperfect, andwith flat plates the operation could not be done except in a verypowerful press and very slowly.

My invention is made for applying an embossing-plate that is a segmentof a cylinder, and hence acts with a rolling motion, and I arrange theparts in such a manner that the leather, skin, or other sheet materialcan be of any desired size, and acted upon conveniently and bysuccessive impressions to emboss the entire skin or material.

In the drawings, Figure l is a side view, partially in section. Fig. 2is a plan partially an elevation of the pressing-segments, the rodsbeing in section at the line at w,"Fig. 1. In Figs. 1 and 2 some of therods are shown as broken off, in order to shorten up the distanceoccupied.

The driving-shaft a is supported by frames 1) b, of any suitablecharacter, between which is the pulley or wheel 0, by which the shaft ais revolved. The cranks d are at the ends of the shaft to, and receivethe connecting-rods 60, attached to the cross'head f, by which saidcross-head is moved back and forth in guides or ways g of the requiredlength, that are supported by suitable frames or standards, k. Thecross-head f becomes the pivot or joint between the connecting-rods eand the links l l and m. m of the sectors 0 and 10. These sectors arepivoted by the shafts a o to the head-blooksr 1', respectively, and therods or columns s 8 connect the head-blocks and form a strong openframe. It is usually preferable to make the portions s s of the frametheir ends through the head and foot blocks, and provided with nuts, soas to adjust accurately the distance between such head and foot blocks.The sectors 0 and p are swung back and forth by the cranks andconnecting-rods, and the parts are placed so that when the cranks passthe horizontal position nearest the sectors the sectors stand in theposition shown in Fig. 1, with their surfaces sufficiently far apart toallow for introducing a skin, hide, or other piece of sheet materialbetween them and moving the same freely for adjusting its position, butas the cranks revolve the sectors are swung and grip the same by thecurved engraved plate or block to, that is fastened to the upper sector,0. I

It is to be understood that the embossingsurface may be in the form ofleaves or ornaments, or roughened or mottled to give the required grainor appearance to the surface of the leather or other. material.

The embossing-plate w is removably attached to the segmental surface ofthe sector '0 by screws or otherwise, so that it may be changed fromtime to time as required.

There are by preference openings at z, through the segmental beds of thesectors 0 into the same, or in which gas-flames or steam can beintroduced to give to the embossing plate or block and to the sectorsthe required heat to insure a perfect embossing operation.

It will now be apparent that the embossing pressure can be very powerfulby the expenditure of only a small amount of power, because theembossing-plate operates with a rolling movement. The material operatedupon is relieved from pressureeach movement, and can he slipped along onthe tables or supports w, so as to bring the surface to the proper placefor receiving the next embossing operation.

I claim as my invention- 1. The combination, with the crosshead, cranks,and links, of the connecting-rods Zm, the sectors 0 p, embossing plateor block, and the head-blocks r and r and their connections,

in the form of tie-rods or columns passing at the parts being arrangedso that the sectors material and gradually press and emboss the 19, sothat heating irons or slugs can be thrust op separate to allow of themovement of the rods and to the sectors the movements specimaterial thatis being embossed, substantially fied.
